Summary

This module was vendored in the previous commit but was not integrated into
the project. This commit performs that integration.

As part of this, we have to add a handful of new dependencies. The new
dependencies all seem quite reasonable. The versions taken were the exact
ones used by the upstream project.

rust/hg-core/Cargo.toml
12	Should we adopt this crate for error handling? I feel like our current solution - although it might need a refactor - is good at forcing the programmer to provide context with finer-grained errors that what you are required to do with `anyhow`. I actually like `anyhow` better than more involved crates, but we will need to have a good "error hygiene" if you will. This seems like a better place to discuss this than the previous patch.

rust/hg-core/Cargo.toml
12	I actually wasn't aware of `anyhow` before writing this patch. And I have to say that I really like `anyhow` because it is simpler than other crates in this space while offering much of the same functionality. I think it is inevitable that we'll want to use a crate like `anyhow` for more advanced error handling. If nothing else, it can help cut down on boilerplate code around error handling.

This revision is now accepted and ready to land.Jan 13 2020, 11:35 AM

This one fails to apply with conflicts in Cargo.lock.

This revision now requires changes to proceed.Jan 13 2020, 11:41 AM

Looks like there are unresolved discussion about error handling here.

I feel like our current solution - although it might need a refactor - is good at forcing the programmer to provide context with finer-grained errors that what you are required to do with `anyhow`. I actually like `anyhow` better than more involved crates, but we will need to have a good "error hygiene" if you will. This seems like a better place to discuss this than the previous patch.

				indygregAuthorUnsubmitted Done I actually wasn't aware of `anyhow` before writing this patch. And I have to say that I really like `anyhow` because it is simpler than other crates in this space while offering much of the same functionality. I think it is inevitable that we'll want to use a crate like `anyhow` for more advanced error handling. If nothing else, it can help cut down on boilerplate code around error handling. indygreg: I actually wasn't aware of `anyhow` before writing this patch. And I have to say that I really…
